WIF Command — WiFi Connection Status

Query the device’s WiFi connection status.

What is it for?

📶 Main use cases:

📊 Verify WiFi connection status
📡 Know the currently connected network
📈 Measure signal strength and quality
🔧 Diagnose connectivity issues
🔍 WiFi infrastructure monitoring

Commands

Operation	Syntax
Query	`QWIF`
Response	`RWIF,pwr,apmode,stationindex,ssid,rssi,signallevel`

Response Fields

Field	Description	Values
pwr	WiFi status	`0` = Inactive, `1` = Active
apmode	Operation mode	`0` = Client (STA), `1` = Access Point (AP)
stationindex	Station index	`0-9`
ssid	Network name	Text
rssi	Signal strength	Value in dBm (negative)
signallevel	Quality level	`0-4`

Signal Levels

Level	Quality	Typical RSSI	Icon
4	Excellent	> -50 dBm	📶
3	Good	-50 to -60 dBm	📶
2	Average	-60 to -70 dBm	📶
1	Weak	-70 to -80 dBm	📶
0	No connection	< -80 dBm	❌

Example

WiFi status query


>QWIF<
>RWIF,1,0,0,VERA AP 4,-74,1<
//    │ │ │    │       │  └─ Signal level: 1 (weak)
//    │ │ │    │       └─ RSSI: -74 dBm
//    │ │ │    └─ Connected network: "VERA AP 4"
//    │ │ └─ Station index: 0
//    │ └─ Mode: 0 (client/Station)
//    └─ WiFi: 1 (active)

An RSSI of -74 dBm indicates weak signal. Consider moving the device closer to the router or using a WiFi repeater.

QWIFN — Scan the visible networks

Since firmware v1.09.26, >QWIFN< scans and lists the WiFi networks the device sees from its position, sorted by signal. It is the tool for diagnosing installations remotely: it answers at a glance whether the customer’s network exists, how much signal reaches the device, and whether the configured SSID is in sight.


>QWIFN<
>RWIFN,*MiRed,-52,6;Vecino,-71,11;(hidden),-80,1<

Lists up to 5 networks, from strongest to weakest signal, in ssid,rssi,canal format separated by ;
The leading * marks the networks that match an SSID configured on the device — if none carries a *, “your network is not in sight” reads straight off
Hidden networks appear as (hidden); repeated SSIDs (mesh) are shown only once with their best signal

Response	Meaning
`RWIFN,OFF`	The device’s WiFi is off
`RWIFN,NONE`	Scan succeeded, no network visible
`RWIFN,ERR`	The scan failed (retry)

The scan is active and blocks the channel that asked for between 1 and 4 seconds. Typical case it uncovers: a configured SSID that does not appear in the list even though the router is right there is usually a 5 GHz network — the device only sees 2.4 GHz.
